Just be aware that what China is currently doing, it will be a lot easier to do for those who have lots of social media accounts.

They are giving all citizens a social credit score which will effect their lives for good or bad.
Seems everyone has their eyes wide shut when it comes to what they post on social media. Funny thing is if you walked up to someone and asked for their phone number, address, date of birth and who their friends are, where they work they would tell you to go away. Yet they will post all this on the internet without a thought about themselves or those around them.
I saw it when someone was served in a large chain pub, within 30 minutes they had the full name, address, phone number, date of birth and pictures of their server in their beach wear from a first name and place of work using nothing but web searches and facebook.
You can now ask Facebook, Amazon etc to provide you with all the data they hold on you. An article in the weekend paper showed what they actually recorded. They keep all your voice searches, text messages, phone calls, photos so they know what you look like, what you sound like, who you talk to for how long. Just to sell that for ad targeting seems overkill.
